| CVE-2017-3790 | Hig | 0.56 | 8.6 | 0.00 | | Feb 1, 2017 | A vulnerability in the received packet parser of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) software could allow an unauthenticated, remote attacker to cause a reload of the affected system, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient size validation of user-supplied data. An attacker could exploit this vulnerability by sending crafted H.224 data in Real-Time Transport Protocol (RTP) packets in an H.323 call. An exploit could allow the attacker to overflow a buffer in a cache that belongs to the received packet parser, which will result in a crash of the application, resulting in a DoS condition. All versions of Cisco Expressway Series Software and Cisco TelePresence VCS Software prior to version X8.8.2 are vulnerable. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Cisco Bug IDs: CSCus99263. |
| CVE-2016-1400 | Hig | 0.49 | 7.5 | 0.01 | | May 25, 2016 | Cisco TelePresence Video Communications Server (VCS) X8.x before X8.7.2 allows remote attackers to cause a denial of service (service disruption) via a crafted URI in a SIP header, aka Bug ID CSCuy43258. |
| CVE-2017-6790 | Med | 0.44 | 6.8 | 0.02 | | Aug 17, 2017 | A vulnerability in the Session Initiation Protocol (SIP) on the Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the targeted appliance. The vulnerability is due to excessive SIP traffic sent to the device. An attacker could exploit this vulnerability by transmitting large volumes of SIP traffic to the VCS. An exploit could allow the attacker to cause a complete DoS condition on the targeted system. Cisco Bug IDs: CSCve32897. |
| CVE-2017-12287 | Med | 0.28 | 4.3 | 0.01 | | Oct 19, 2017 | A vulnerability in the cluster database (CDB) management component of Cisco Expressway Series Software and Cisco TelePresence Video Communication Server (VCS) Software could allow an authenticated, remote attacker to cause the CDB process on an affected system to restart unexpectedly, resulting in a temporary denial of service (DoS) condition. The vulnerability is due to incomplete input validation of URL requests by the REST API of the affected software. An attacker could exploit this vulnerability by sending a crafted URL to the REST API of the affected software on an affected system. A successful exploit could allow the attacker to cause the CDB process on the affected system to restart unexpectedly, resulting in a temporary DoS condition. Cisco Bug IDs: CSCve77571. |
| CVE-2015-0752 | | 0.00 | — | 0.00 | | May 29, 2015 | Cross-site scripting (XSS) vulnerability in Cisco TelePresence Video Communication Server (VCS) X8.5.1 allows remote attackers to inject arbitrary web script or HTML via a crafted URL, aka Bug ID CSCut27635. |
| CVE-2015-0579 | | 0.00 | — | 0.01 | | Jan 14, 2015 | Cisco TelePresence Video Communication Server (VCS) and Cisco Expressway allow remote attackers to cause a denial of service (memory and CPU consumption, and partial outage) via crafted SIP packets, aka Bug ID CSCur12473. |
| CVE-2014-0675 | | 0.00 | — | 0.00 | | Jan 23, 2014 | The Expressway component in Cisco TelePresence Video Communication Server (VCS) uses the same default X.509 certificate across different customers' installations, which makes it easier for remote attackers to conduct man-in-the-middle attacks against SSL sessions by leveraging the certificate's trust relationship, aka Bug ID CSCue07471. |
| CVE-2012-0331 | | 0.00 | — | 0.00 | | Mar 1, 2012 | Cisco TelePresence Video Communication Server with software before X7.0.1 allows remote attackers to cause a denial of service (device crash) via a crafted SIP packet, as demonstrated by a SIP INVITE message from a Tandberg device, aka Bug ID CSCtq73319. |
| CVE-2012-0330 | | 0.00 | — | 0.00 | | Mar 1, 2012 | Cisco TelePresence Video Communication Server with software before X7.0.1 allows remote attackers to cause a denial of service (device crash) via a malformed SIP message, aka Bug ID CSCtr20426. |
